A spy saw Cohen wearing a plain black jacket, slacks and thick
sole lace-ups near the main entrance.

Cohen was also seen fumbling for his tickets. Our spy thought
Christie's should have just recognized him and let him in.

"They were stalling him for tickets. Idiots, when someone pushes
hundreds of millions worth of art business through their
auctioneer block they should have an effing portrait of him in
the 'Hall of Honor' and know him by a face," the spy tells us.
